API 2448 Inline Fully Discrete, Loaded 24, With Automation and 529C. (Used)

The API 2448 Recording and Mixing Console (Used)

This API 2448 was purchased new in Sept 2022.  The console is in excellent condition.  The Spectrasonics modules in the jukebox may be included in the purchase.  The remainder of the 5 year warranty will be transferred to the new owner.

The API Audio 2448 is an analog console designed to the same standard of excellence as the 1608, Legacy AXS, and Vision consoles. Featuring dual audio paths, this is a true inline console with 2 complete audio paths in every channel for simultaneous analog tracking as well as monitoring. Bringing a nearly 50 year legacy of combining functionality and reliability with the unmistakable warmth of the API sound to you today! Read more about the API 2448 below:

Signal Paths

Each 2448 channel has 2 signal paths: the Large Fader path (input and tracking) and the Small Fader path (playback & monitoring). Using the Program Bus to combine these 2 paths with the 4 Stereo Returns provides 56 channels of audio for mixdown. Contained within the 648C channel module, either path can be used for tracking or mixing, depending on your needs.

Large Fader

The Large Fader path has everything you need to track and route your audio signal chain. With what is essentially a classic API 212L mic pre, the preamp section provides 48v phantom power, a -20dB pad, a peak input LED , phase reverse, as well as up to +55dB of gain.

The default signal is a balanced, Low-Z Line Input, with a -6dB pad switch. The path then flows to the API 550A equalizer. There’s a polarity reverse and/or High Pass Filter of -3dB at 50Hz. The signal can be panned between Left & Right Program Busses or Odd & Even selections of the 8 Summing Buses (when engaged). The signal can be soloed or muted as needed.

The Large Fader path feeds the Direct Outs and 8 Auxiliary Sends. The Aux Sends are 4 mono and 2 stereo. Level control, on/off switch, and a pan pot for the stereo sends on each send. All sends can be either pre- or post-fader. You can also route Aux Send 7/8 directly to Summing Buses 1-4.

Small Fader

The Small Fader path provides everything you need to mix your audio signals. The level control (up to +10dB of gain) uses a rotary pot, rather than a fader. This can be bypassed to let audio pass at unity gain.

The default signal to the Small Fader path is the output of the mic preamp. Also, the Alternate Line Input can be chosen to replace the mic preamp feed with a Line level input via the D-sub connector.

There’s a peak LED indicator for the input signal, and that also be sent to the classic API 550A equalizer. It can then have its polarity reversed and/or run through a High Pass Filter of -3dB at 50Hz. The signal can be panned between the Left & Right Program Buses (by default) or the Odd & Even selections of the 8 Summing Buses (when engaged); it can also be routed to the Direct Outs or to Auxes 5-8. The signal can also be Soloed or Muted.

2448 Master Section

The Master Section of the API 2448 has an extensive set of tools allowing for control and processing your signals for both tracking and mixing. This section houses the controls for the Auxiliary Sends, Summing Buses, Solo Bus, Oscillator, Talkback, Control Room monitoring and the Stereo Returns.

For processing and adding color to your sound, there are four Stereo Returns located on the 265C module; these can take their input from either a D-sub Line Level (default), the 8 internal Auxiliary Buses or the 8 500 Series slots in the Master Section. These inputs can be summed to Mono, after which a Stereo Insert Return is also available. This is followed by a 100mm long-throw fader with up to +10dB of gain. The post-fader output is mutable, and can be assigned to the Program Bus or to the Summing Buses 7 & 8.

Stereo Bus Compressor

The 529C Stereo Bus Compressor is based on the wildly popular 2500 model. The 529C was the first dual-slot 500 Series module ever made by API. It’s a perfect fit for the 2448.

Loaded with 2520 and 2510 discrete op amps, the 529C was designed to provide myriad compression parameters in a tight space. Additionally, the Old/New option even gives you a choice between old-school feedback compression or new school feed-forward style.

Aux Sends

The 265C contains 8 Auxiliary Sends. There are 4 pairs above the Stereo Returns (sends 1-2 are for Stereo Return 1 et.al.). Each Aux Send has it’s own on/off switch, and provides for an External Input, Level control up to +6dB, Solo control, Talkback insertion (headphone feeds), VU meter routing, as well as balanced, line-level output from the D-sub connector.

Summing Bus

The 168C Summing Bus Module contains the routing and control for all 8 buses, as well as an external input to the Program Bus. Each Summing Bus has its own on/off switch, Level pot (up to unity gain), Solo button, and assignments for the Left & Right Program Buses (these can be overridden by the rear panel ¼” TRS input switching jacks).

Control Room

The 845C Control Room Monitor Control is the ultimate tool for routing and monitoring your tracking and mixing. Choose any source to monitor among the Program Bus, Aux Sends, or external 6-track playback for 5.1 monitoring. These are fed to the output control section, where it can be switched off, attenuated via the Dim Level pot, summed to mono, and routed to the main speakers, as well as two lternative monitoring systems.

The 268C Output Master is your main monitoring selector. The 268C’s six Monitor outs can be switched on/off and also allows calibration of the trim pots before final send to the rear panel Control Room Output connectors.

Stereo Program Bus Master

The 268C Stereo Program Bus Master is the last link in the audio signal chain. The 268C takes inputs from the Stereo Bus Compressor, as well as the Program Inserts. A Trim control with calibration sets the output level of the Program Bus. There’s also and On/Off switch. The 440C Master Fader and Inserts can also be upgraded with automation (optional).

Analog VU Meter Bridge

The API 2448 comes with a full analog, illuminated VU meter bridge. Each VU meter is presented in black to red scale on a yellow background for easy visibility. Each Input channel has its own medium-size VU meter, with the first 8 doubling as meters for the Summing Buses. The Master Section also has 8 Auxes and 4 Stereo Returns with their own set of small meters. Finally, the Stereo Program Bus is displayed has a pair of large-size meters.

 

Real Panel Connectivity

The rear panel of the 2448 has all the connectivity you need to interface with your studio equipment:

• 3-pin XLR inputs for Mic, Line, and 6-track playback; also L/R Outputs for the Program Bus, Alt 1 & 2 Control Room Monitors, and the 5.1 surround channels.
• 25-pin D-sub connectors for Direct Outs, Aux Send and Bus Mix Outs, and Inputs for the Stereo Return, 6-track playback, and all of the Alt Line Inputs to each channel.
• ¼” TRS jacks for the Send/Return patching of the 2448: Large and Small Fader Path Sends & Returns; the Bus Mix Input, the Aux Sends External Input, the Stereo Return Inserts, the Return 500 Series slots, and the Program Bus Insert Send/Return.

And finally, ports for interfacing with MIDI, HDMI, USB, SMPTE and Automation.

Final Touch™ Automation

The Final Touch™ moving-fader and switch automation system can be ordered or added later as an upgrade. Final Touch™ is a cross-platform system that provides moving faders and automated Mute or Insert for all Channels, Stereo Returns and the Program Master, as well as 2 automated Control Group Masters, and MIDI and SMPTE timecode synchronization. A built-in computer and touchscreen provide the interface, and no external computer is required.
